TWINE CUTTER Filed June 4, i929 f r 323m (WWW Patented Aug. 25, 1931 v UNITED STATES HERBERT W. FENTON, F DOWAGIAC, MICHIGAN TWINE Application filed June 4,

My invention relates to improvements in twine-cutters, and more particularly to that a string, thread, or any other cord material.

My improved twine cutter, although capable of use as above stated, is particularly designed and constructed for use in tying up grape vines, and other plants necessary 1 to train on suitable supports, as it is worn on the hand in such a manner that it will not interfere with the tying operation, but will be handy for cutting the twine or other cord material used for such purpose after each tying operation.

My invention has for one of its objects the production of a twine cutter of novel and simple construction associated with a I ring or ring support that it can be adjusted 2 to any desired angle with reference to the axis of said ring or support, or be posltloned parallel therewith, and regardless of its position, beretained as adjusted.

Another object of my invention is the provision ofa double edge cutter, in a twine cutter, so that twine or other cord materlal can be cut by either of two opposite movements given the device, which is a very desirable feature of my invention, when cutting the'twine after tying grape vines to their supports, due to the fact that oftentimes surrounding partsinterfere with the cutting action if the device is moved in a certain direction, whereas freedom of action and. non-interference by surrounding parts would be assured if the device were moved in the opposite direction.

1 A further object of my invention is the production of a cutter element which is readily removable from its holder so that it can be re-sharpened when dull, or be re- 7 placed with another cutter element.

With the above and other objects to appear hereinafter, my invention consists in i the novel features of construction and in CUTTER 1929. Serial No. 368,230.

the arrangement and combination of parts to be hereinafter described andmore particularly pointed out in the subjoined claims. In the drawings:

Fig. 1 is a perspective view of my improved twine cutter, showing the same as worn on a finger of the user.

Fig. 2 is a side elevation of the same.

Fig. 3 is a plan view.

Fig. 4 is an enlarged section, taken on line 44, Fig. 2.

Fig. 5 is a section, taken on line 55, Fig. 1, on a reduced scale.

Fig. 6 is a detachable perspective view of the cutter element.

Reference being had to the drawings in detail, the numeral 7 designates a carrying member or object. for the cutter proper, in the form of a finger ring which may be constructed of any suitable material and in different sizes; it being provided with a tapped opening 8 in its surrounding wall for the reception of a screw-threaded stud 9 extending inwardly from a blade-support or holder 10. This blade support, or cutter-element support as it may be termed, may be varied in shape, but preferably has two wings 11 extending from opposite sides of, a plane passing axially through the screw-threaded stud 9. Said support is comparatively thin and has opposite ends rounded inwardly, or toward the finger ring 7, as at 12, to prevent catching the twine or becoming entangled with other objects, while the inner edge thereof, or more particularly, the inner edges of the two wings are notched or deeply concaved, as at 13, to expose comparatively large portions of the blade or cutter-element to be'pre'sently described. y

The blade or cutter-element supportlo is slotted, as at 14:, from its outer edge inward- 1y toward the screw-threaded stud 9, so that substantially two side members 15, 16 are provided which are spaced apart a suflicient distance to receive a blade or cutter-element 17 between them. I

The blade or cutter-element is substantially triangular in shape, as shown in Fig. 6; two edges 18 thereof being sharp and being exposed at the notched portions of the support 10. Attention is here invited to the fact that the support or holder 10 conforms somewhat to the outline of the blade or cuting-element, except for the notches 13 in said support and its projecting stud 9; and that the slot 14 in said support or holder terminates a short distance from the screw-threaded stud 9 in a wall 19 having a retainer lug 20 extending into said slot. The two sharpened or cutting edges 18 of the blade or cutting-element are disposed at obtuse angles to each other and separated by an edge portion 21 conforming to the shape of the inner wall 19 of the slot 14: in the support 10. It therefore has a notch 22 extending inwardly from the edge portion 21 which receives the retainer lug 20 extending into said slot and forming part of said wall.

Arranged in the side members 15 and 16 of the support or holder 10 are alined screw holes 23, 24, respectively, and formed in the blade or cutting-element is a screw hole 25 which registers with the screw holes 23 and 24. A securing screw 26 is passed through the screw-hole 28 in one side member, which is countersunk to receive the head of sald screw, and through the screw hole 25 in the blade or cutter-element and it is screw threaded into the screw-hole 2st in the other side member, which screw-hole is tapped for the purpose.

When the blade or cutter-element is positioned within the support or holder 10, it is clamped between the side members 15 and 16, and in the event that the securing screw 26 becomes loosened the blade is held against is threaded. This jamb-nut locks against 1 the outer surface of the ring and prevents turning of the screw stud and consequently swiveling movement of the support or hold- VVhen said jamb-nut is loosened from contact with the finger ring, the-blade support or holder 10 may be turned into any position, either to the position shown in full lines in Fig. 3, at right angles thereto, or into any intermediate angular position, as shown for example by dotted lines .in said figure. The tightening of the jamb-nut against the finger ring will retain the support in the desired adjusted position.

It will be quite apparent that when the blade or cutter-element is in any particular position with reference to the finger ring it may be'most convenlent for one user and exceedingly awkward for another. The 0- sition and angle of the twine 28 or 01: er cord-like material to be cut may suggest a change of angle of the blade by the same user, and he may find it easier to cut with one exposed cutting edge than the other, depending on the direction of the strand of twine to be cut; this being clearly shown in Fig. 1.

The double cutting edge exposure, with one cutting edge at an angle to the other, is therefore a decided advantage in the use of this invention, and particularly the location of cutting edges at opposite sides of the center of the support, or more particularly stated with reference to the finger ring, at opposite sides of a radial plane.

"This device may be used on any finger, and if desired, tWo or more finger rlngs may be furnished with each blade support; thus en-.

abling diiferent persons to use the same finger support With finger rings to fit the fingers of the different users. I

It may also be stated, that for some kinds of work, it may be found of advantage to use whether used on the outer or inner side of the hand andregardless of the finger it is used on, the device is easy to operate by eithera right or left hand user; its double universal to meet all conditions.

Having thus described my invention, what I claim is 1. A twine cutter, comprising a blade the device on the palm-side of the hand; but I .95 cutting edge and its adjustability making it holder of substantially triangular shape and having its inner edge formed by two sides of the triangle and its outer edge by the third side, said holder being slotted from its outer edge inwardly through the end portion of said inner edge to form two spaced side members connected integrally at a point centrally between the two first mentioned sides of the triangle, said side members being provided with alined holes, a cutting blade positioned between said side members andhaving a hole registering with theholes in said side members, and fastening means entered in the holes of said side members and said cutting blade, said cutting blade having cutting edges exposed at the inner edge of said ,lblade-holder.

2. In combination with a finger ring, a

' blade-holder having a supporting stud centrally between its ends entered in said ring desired position, and acutting blade carried by said blade-holder] and. having cutting 12 edges exposed at opposite'sides of. said stud, said cutting edges being atan angleto each other and capable of 'being disposed parallel with a plane passingaxially through .the ring or at any angle thereto.

3. A twine cutter, comprising a bladeholder of substantially triangular shape and having two of its sides forming the inner edge of said holder and the remaining side the outer edge, said holder being slotted from its outer edge inwardly to form two spaced side members for said holder connected together at its inneredge centrally between the ends of said holder, said central 7 connection forming the inner wall of the slot so formed and said inner wall having a retainer lug between its ends extending into said slot, said slot opening through portions of the two first-mentioned sides of the triangle and said side members having alined screw holes near the outer edge of the holder, a cutting blade of substantially triangular formation held between said side members and having a screw hole registering with the screw holes in said side members and a notch at its inner edge into which said retainer lug fits, the cutting edges of said blade being exposed at the inner edge of said blade-holder at opposite sides of said notch and retainer lug, and a screw entered in said registering screw holes and clamping said blade between said side members.

In testimony whereof, I afiix my signature.
